tracking

Adjusts the spacing between individual characters (glyphs) in text rendering.

This variable represents the value for additional tracking, applied to influence the overall spacing or "kern" between consecutive characters in a text string. A positive value increases the spacing, while a negative value decreases it.

Tracking affects the visual appearance and layout of rendered text, playing a crucial role in typography and text styling. When rendering text, this value is taken into account alongside other metrics such as glyph advance width and kerning.
